4mmc, cleaning procedure

[PeterKeta]

Hello! I've come across this kind of 4mmc (pic related), which does not remind me of other forms I've seen it in earlier.
It's not advised to be nasally administrated by the salesman. Probably not IV as well, i would not let anyone risk it.
I've looked into the crystallization guide but unfortunately I'll have issues cooking this in IPA because of the fumes in the apartment.
What's the correct procedure for cleaning this? Primary looking for pointers from someone with (perhaps) experience of the 4mmc of the picture.

Either cold IPA, just solve it and let it evaporate?
Or acetone? just rinse it through and filter it?

My hope is to get this fit for nasal administration.

Cześć! Natknąłem się na tego rodzaju 4mmc (zdjęcie), które nie przypomina mi innych form, w których widziałem je wcześniej.
Nie zaleca się podawania donosowego przez sprzedawcę. Prawdopodobnie nie IV również, nie pozwolę nikomu ryzykować.
Zajrzałem do przewodnika po krystalizacji, ale niestety będę miał problemy z gotowaniem tego w IPA z powodu oparów w mieszkaniu.
Jaka jest prawidłowa procedura czyszczenia tego? Przede wszystkim szukam wskazówek od kogoś, kto ma (być może) doświadczenie z 4 mmc obrazu.

Albo zimny IPA, po prostu go rozpuść i pozwól mu odparować?
Albo aceton? wystarczy przepłukać i przefiltrować?

Mam nadzieję, że uda mi się to nadawać do podawania donosowego.

PeterKetaAcetone only wash and finish

PeterKetaWouldn't it be better to just not use this substance and throw it away?

The IPA can be heated in a water bath in a sealed jar, and this 4mmc can be placed there beforehand. Stir the contents of the jar until the 4mmc is completely dissolved, then cool the contents and place in the freezer for 8+ hours. After precipitation, filter through a paper filter.

Marvin Popcorn SuttonThis sounds very good. May i just ask how hot the IPA could be? And the water bath is it supposed to be of recently boiled water? Is coffee filter enough or do you have another suggestion ? Also how solvent is recommended? Just enough for the content being solved?
Thanks!

Hi,

I had batches looking quite similar over the last year (maybe the same...AT? )
If so, your salesman is right - this stuff is unsnortable Then, a simple cold acetone wash will not be sufficient. While it will come out white and dry (the moist/gooey stuff will be in solution with the acetone drain), it will for a large part keep its peppery sting and therefore tearjerking properties.
However, when properly recrystallized, it will come out as transparent to white crystals with hardly any noticeable odor and feeling pleasantly mild to the nose.

I'd go with a mix of distilled H2O and IPA. The more IPA in the mix, the finer and more elongated (needle shaped) the crystals are going to grow.
If you plan to go with simple coffee filters later on, you'll want to grow some descent crystals of a size that won't slip through the pores. I'd therefore recommend a ratio of something between 70:30 to 50:50 Water:IPA
Heat the mix (loosely covered with a lid) to a slight boiling temperature (~70-80•C) and then add dropwise/in small portions to a second vessel already containing the prepared 4-MMC while stirring. Stop adding liquid when all solids have become completely dissolved (no need to boil the solution extensively! Place the second vessel in a hot water bath while this though, to avoid cooling too fast and thereby using more solvent than actually required, see below).

2-3 ml water+IPA solvent mix per gram will do. With this procedure, fumes/smell will be minimal.
Be careful not to add too much liquid, as it will result in an unnecessarily elongated process time and maybe reduced yield (if reXing mainly on cooling).
And then, boiling off excess solvent with the drone already being in solution will definitely evoke aggressively stinking fumes

Finally, let it cool down slowly to room temperature and leave it undisturbed while that. Be patient, as formation of first crystals might tale some hours. When crystal growth at room temp comes to a halt, carefully transfer to the fridge for a few hours to squeeze out more out of the solution.
Finally filter off remaining solution (keep it and let it evaporate, as there will be still meph in solution that will eventuslly percipate out in finer crystals (which hovever will be laced with more impurities...you can clean those later in a second step).
Wash yielded crystals with a few drops of ice cold acetone from the freezer. Let dry and enjoy
Good Luck

P.S.: Water+Ethanol mix produces even nicer crystals, Ethanol is a bit more tricky however, as it evaporates slower than IPA ->more exact solvent/solvate ratio needs to be met, or you'll end up waiting a week+ to yielding or boiling off, and you don't want that. Furthermore, "oiling out" will happen more often with EtOH than with IPA ime. And you'll want this even less

hotelierThis is somewhat odd but I also have trouble obtaining large crystals but in my case I am aware it's mostly due to impatience.
